How much for a stud partition wall?
Build a partition — enter the size and stud spacing and get the timber lengths for the frame (studs, plates and noggins), the plasterboard for one or both sides, and the insulation between the studs. Free, no sign-up.
A guide, not a guarantee. We count vertical studs at your spacing plus one end stud, a top and bottom plate, and a row of noggins (two rows over 2.4 m), then divide the total length by your timber size — real offcuts mean you may need a touch more. Each doorway adds extra for the frame. Plasterboard is sized for the chosen number of sides plus wastage. Insulation, the head/sole plate fixings, drywall screws, scrim tape and jointing compound are all extra. A load-bearing or separating wall needs a proper design and the right fire/acoustic spec. Nothing you type leaves your browser.
The frame, the boards, the fill.
The frame first. A stud wall is a timber frame: vertical studs at regular centres between a top and a bottom plate, with horizontal noggins to stiffen them. We count a stud every 400 or 600 mm plus one at the end, the two plates, and a row of noggins (two rows over 2.4 m), then divide the total length by the timber size you buy.
Why 400 mm. Plasterboard is 1.2 m wide, so studs at 400 mm centres land neatly under every board edge and the middle — the standard for a sound, flat wall. 600 mm uses less timber but only suits light, non-structural areas.
The boards. A normal partition is boarded both sides. We take the wall area, double it for two sides, add wastage and divide by your board size to get the number of sheets.
The fill. Insulation (acoustic mineral wool is usual) goes between the studs to deaden sound — we give the area to fill. Buy it to suit the stud depth, usually 70–100 mm.
What this leaves out. Fixings into the floor and ceiling, drywall screws, scrim tape and jointing compound, any door lining and architrave, and the structural design itself. A load-bearing or separating (between-dwelling) wall needs designing properly with the right fire and acoustic build-up — this tool is for a simple internal partition.
